Thats is really an awesome example of SlideIn and SlideOut. I have one question... How can we convert this left to right sequence to Top to bottom?

Android Er said...

hello,

please read Implement slide top-down vertical animation.

Ali Bin Abid said...

Thanks Mate really helpful :)
I have one that why the image take a stop in the middle of the screen??? Even if I disable the the Pause action it still doesn't work. Any idea or I am missing something.

Warm Regards.

Hello Ali Bin Abid,

I think it's the delay between AnimationEnd -> Listener -> andother Animation start.

Hi Android Er....
If this is the case then how can we decrease this delay???? I am completely new so please ignore if I sound stupid.

Hello Ali Bin Abid,

If you want the animation from left-in to right-out only, without stop on center, you can create your animation.

Refer to Implement slide top-down vertical animation.

You can create your own animation with fromXDelta="-50%" and toXDelta="50%"
